Hello

Pls Service the LCD Panels of the Projector, Also check the Fly-Eye lens, just next to Lamp unit. This will solve your problem. if it's not then the only solution is Replacement of LCD Panels, But Must check or replace the external RGB Cable first befor doing all this exercise.

Sounds like one of those problems only cureable with expert knowledge of for example Chroma feed , Lcd function , lamp luminence, not to be a killjoy but it sounds like this is one for the engineers an estimate should be free and even if you dont have it fixed you'll know whats wrong if you want to do it yourself providing you have adequate training of course ....

Suddenly, benq mx511 has white pixels showing up....multiplying every day...now the projected image consists of 50% snow.


It probably has the same DLP chip as my Mitsubishi television. The mirrors in the chip set get stuck and create the white spots. There is no way to fix this other than replacing the DLP chip.

My Acer projector P5260E started gaining tiny white spots that multiplied over time and now has almost completely covered 40% of my screen. I've installed a new lamp and still have the white spots. Not as...


I have the same problem. All of a sudden there are plenty white dots all around the screen. As if 1/3 of the pixels are burnt. It cannot be the lamp because it is still as bright as before. It must be the internal screen or whatever. The "Troubleshooting" section of the user manual does not mention such thing.
